Oxygen inhalation is not simple, these 5 misunderstandings, see you "step on the pit"?
With the improvement of health awareness, many families have purchased oxygen generators, ventilators, blood oxygen meters and other oxygen therapy equipment, but oxygen therapy seems to be very simple, which knowledge is also a lot: which people need to take oxygen? What do you need to pay attention to when using oxygen generator? How to perform oxygen therapy scientifically?
Today, we are going to talk about the 5 major misunderstandings of oxygen inhalation, and see if there is a "step pit"!
Who needs home oxygen therapy?
People suffering from hypoxic diseases: patients with acute attacks of bronchial asthma, interstitial lung disease, COPD, emphysema, neuromuscular or chest wall diseases.
- Cardiovascular disease patients with hypoxemia: such as heart failure, pulmonary hypertension, angina, etc.
- People prone to hypoxia: middle-aged and elderly, pregnant women, students engaged in mental work for a long time, white-collar workers and so on.
- People entering plateau areas: due to the thin oxygen in the environment, the oxygen content entering the body is low, and it is easy to appear high altitude pulmonary edema, high altitude hypoxia, etc., and oxygen therapy is needed as soon as possible.
How long is it appropriate to take oxygen every day?
The flow rate of long-term oxygen therapy for COPD patients is generally recommended to be 1.0~2.0 L/ min, and the duration of daily oxygen inhalation is >15 hours.
For non-COPD patients, oxygen inhalation varies from a few hours to more than ten hours a day, mainly to control the oxygen flow rate and extend the oxygen inhalation time, the longer the oxygen inhalation time, the greater the benefit of patients.
Is the higher the oxygen saturation the better?
Copd patients require low-flow oxygen, and the blood oxygen saturation is above 90%. It is generally not recommended that patients with COPD take high levels of oxygen, which can cause further hypoventilation, inhibit the respiratory center, and cause carbon dioxide paralysis and apnea.
In general patients, the blood oxygen saturation can be controlled at 94%-98% to benefit, and on the basis of the blood oxygen saturation standard, the oxygen absorption concentration should be reduced as far as possible, otherwise it is easy to cause hyperoxemia (PaO2 > 120mmHg).
How to choose the right oxygen concentration?
- Low concentration oxygen (inhaled oxygen concentration < 40%) : used for COPD patients with CO2 retention, can avoid inhibiting the respiratory center, aggravate hypercapnia;
- Medium concentration oxygen (inhaled oxygen concentration 40%-60%) and high concentration oxygen (inhaled oxygen concentration > 60%) : suitable for patients with simple hypoxemia without significant CO2 retention, that is, type I respiratory failure;
- Pure oxygen inhalation (inhaled oxygen concentration 100%) : generally used before and after the establishment of artificial airway; Before and after sputum aspiration during mechanical ventilation; For patients with severe refractory hypoxemia, high concentration or pure oxygen inhalation therapy was given to save lives, and the oxygen concentration was gradually reduced after the condition improved.
How to regulate and scientific oxygen therapy?
- Avoid long-term high concentration oxygen inhalation, high concentration oxygen inhalation (> 60%) for more than 24 hours may occur oxygen poisoning.
- Home oxygen therapy needs to pay attention to the heating and humidification of oxygen to protect the trachea and bronchial mucosa, maintain cilia movement, and promote sputum discharge.
- Pay attention to the regular disinfection of oxygen inhalation pipes to avoid cross infection.
- Never smoke or burn items in case of fire and explosion.
